I was chosen to attend a campus recruiting event. The interview was entirely behavioral. They did not expect you to know anything about control systems. The recruiter was surprised to see that I had done multiple projects on control systems. The interview was more about the recruiter explaining the job description than a serious interview. Go prepared with questions otherwise your not going to make an impression.
